Summary: In this study, NaMMT clay incorporated and maleic acid crosslinked polyvinyl alcohol-chitosan interpenetrating network nanocomposite membranes were prepared for the dehydration of acetone. The membranes were characterized using various analytical techniques, and the effects of clay, chitosan, and maleic acid on water flux and separation factor were statistically optimized. The optimal membrane composition was found to be 39.3 wt% chitosan, 3 wt% maleic acid, and NaMMT nanoclay.

Summary: In this study, a nanogel composite was developed by modifying Cloisite 30B nanoclay and embedding it within a commercial epoxy resin to create a self-healing epoxy-based coating. The incorporation of nanogel slightly decreased the mechanical properties of the epoxy coatings, but it provided high corrosion resistance with a self-healing efficiency of 99.88%. The nanogel composite showed successful synthesis and dispersion, indicating promising potential for corrosion protection applications.

Summary: Based on the solution-diffusion model, the development of thin-film composite membranes with hydrophilic surface and hydrophobic internal structure is more favorable for the adsorption and desorption of water molecules, overcoming the trade-off effect between flux and separation selectivity. The hydrophilic modification of the TFC membranes significantly improves the ethanol dehydration performance.

Summary: To improve the selectivity and permeability of alcohol dehydration, hydrophilic zirconium-based NU-906 nanoparticles were incorporated into chitosan to fabricate NU-906/CS mixed matrix membranes. The hybrid membranes showed excellent water affinity and structural stability, leading to enhanced water selectivity and permeability. The optimized membrane with 5.0 wt% NU-906 achieved a high flux of 1086 g/(m(2).h) and an excellent separation factor of 2651 for 90 wt% ethanol dehydration at 76 degrees C. This research expands the range of MOFs available for the fabrication of mixed matrix membranes and provides new options for organic solvent pervaporation dehydration.

Summary: This study utilizes membrane pervaporation to recover ethylene glycol by dehydrating water from a mixture of ethylene glycol and water. Two hydrophilic derivatives from the polymer of intrinsic microporosity (PIM-1) were suggested as feasible membrane materials, which showed increased water sorption capacity and tenfold greater water permeability compared to pure PIM-1. The modified membranes retained a water content of 99.9% in the permeate, demonstrating a simple method for modifying suitable dehydration materials while maintaining the original polymer's structural quality.

Summary: Novel membranes based on biopolymers were developed for pervaporation dehydration of isopropanol by employing surface and bulk modifications, with improvements in transport characteristics observed. The introduction of fullerenol and cross-linking agents, as well as layer-by-layer deposition of polyelectrolytes on supported membrane surface, led to enhanced permeation flux but with lower selectivity.

Summary: Plastics are widely used for food packaging, but most packaging is disposable, resulting in significant waste generation and environmental degradation. The degradation processes are influenced by various factors, including mechanical forces, temperature, light, and chemical and biological factors. These processes result in the formation of microplastics, which can further degrade into small-molecule compounds. Microplastics and additives used in plastic processing can have negative effects on human and animal health. Understanding the degradation processes of packaging waste and their products is crucial for determining the negative consequences of microplastics.

Summary: This study investigates the possibility of using chitin from the molts of Tenebrio molitor to remove anionic and cationic dyes from aqueous solutions. The results show that the sorption efficiency of chitin for anionic dyes is highest at pH 2-3, while for cationic dyes it is highest at pH 6. The maximum sorption capacity of chitin for anionic dyes is higher than some carbon-based materials.

Summary: Thermal feathering and fluorination are used to create durable, transparent hydrophobic, superhydrophobic, and omniphobic surfaces with modern carbon nanomaterials, such as single-walled carbon nanohorns and carbon nanoonions, in polyethylene. The reactivity of single-walled carbon nanohorns is enhanced by their conversion into open sensu shaped graphene oxide. Omniphobicity is then introduced through fluorination, resulting in new superhydrophobic and hydrophobic translucent surfaces. Spectroscopy, tribological analysis, and contact angle measurements are utilized to characterize these surfaces.

Summary: In this study, a low-energy membrane emulsification process was developed for the preparation of water-in-oil (W/O) chitosan emulsions with a narrow droplet size distribution. The effects of emulsifier concentration, rotation speed, and chitosan concentration on droplet size and stability of emulsions were evaluated. The prepared emulsion showed a monodispersed pH responsive behavior with a droplet size of 300 ± 40 nm. The release of Vitamin B5 (calcium pantothenate) from the emulsion was temperature and pH dependent.

Summary: Color is a prime feature that directly influences consumers' attraction and choice of food. The flavor, safety, and nutritional value of food products are closely related to their color. Natural and synthetic colorants have diverse applications in various industries. While synthetic colorants are popular due to their stability and affordability, previous studies have highlighted their toxicological, carcinogenic effects, hypersensitivity reactions, and behavioral changes. In contrast, natural colorants have nutraceutical qualities and beneficial properties such as antioxidants, anti-inflammatory effects, and health benefits.
